今天收到一封citizens bank的邮件，说用citizens的debit card，用够20次 purchase
without PIN可以拿到一个 COMPANION AIRLINE CERTIFICATE，也没说价值多少。这个
是什么东西啊？值得试试吗？

Choose Credit
CHOOSE “CREDIT” and sign for your
purchases when you use your card at checkout.
EARN A COMPANION AIRLINE CERTIFICATE¹ after making just 20
qualifying purchases².
